BEND OR PIPE CONNECTION FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 718,444, dated January 13, 1903.

Application filed July 5, 1902. Serial No. 114,395. (No model.)

To all whom, it may concern:

Be it known that we, EDWARD FLEMING and AUGUSTUS FLEMING, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinven ted certain new and useful Improvements in Bends or Pipe Connections for Water- Closets, of which the following is a specification.

This invention relates to improvements in pipe connections, and while it is more especially intended to be used for connecting the water-closet bowl to the soil or waste pipe,

' yet it is applicable for otherpurposes; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The objects of our invention are to provide a pipe connection which shall be simple and inexpensive in construction, tight fitting, so as to prevent leakage, strong, durable, and readily attached or detached; also, to provide a pipe connection of the above-described character which will occupy little vertical space between the floor on which the closetbowl stands or rests and the ceiling of the next room below the same and to which the flushing and venting pipes may be easily connected with the main pipe or elbow.

Another object of our invention is to so construct the connection as to dispense with the ordinary lead pipe whichjis now generally used and which is objectionable on account of the difficulty of uniting it by means of solder or otherwise with the difierent parts, and also on account of its being gnawed by rats, as is well known.

A further object of the invention isto provide the elbow or bend with circumferential grooves, so that it may be broken off at said points in order to shorten it to the desired length.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which our invention pertains to make and use the same, we will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1 is a vertical sectional view of a portion of a water-closet bowl, a part of the flooring on which it rests, and our pipe connection in position thereon. Fig. 2 is an end view in elevation of the elbow or bend. Fig. 3 is a top plan view of the externally-screwthreaded and flanged connecting-pipe. Fig. 4 is an enlarged perspective view of a portion of the flange of said pipe, showing one of the openings therein for the securing-bolts. Fig. 5 is a detail view of one of said bolts, and Fig. 6 is a similar view of the upper portion of the connecting-pipe.

Similar letters refer to like parts throughout the different views of the drawings.

A represents a portion of a well-known form of water-closet bowl, which is provided at its lower portion with a horizontally-ex tending flange a, which flange is downturned at its outer edge, as at a, thus forming a cup or recess for the reception of the horizontallyextending flange B on the upper end of the connecting-pipe B, which pipe is externally screw-threaded, as is clearly shown in Fig. 1 of the drawings.

The flange B is provided with a series of vertical openings for the reception of the securing-boltsc, which are used for fastening the flange B of the said pipe to the flange a of the bowl. Each of the apertures in the flange B comprises an enlarged opening I), usually rectangular in form, as shown, and a slot 1), which communicates with the opening 1) and is somewhat narrower at its top than said opening. In other words, the slot 1) or extension of the opening I? is provided with downwardly and outwardly inclined walls b which afford a downwardly-flaring opening for the reception of the tapered heads 0 on each of the bolts.

The bend or elbow C is preferably made of cast-iron and has in its upward extension an internally-screw-threaded opening (1, which is annularly enlarged, as at d and (1 which enlarged portionsare unthreaded, as shown. The lower or horizontal portion of the elbow or bend C may be connected to the soil-pipe (not shown) in any suitable manner, and in order to easily shorten said portion we provide it on its external portion with a series of circumferential grooves e, in one of which a chisel or other tool may be inserted, when by striking the same the pipe may be broken off at said point.

The adjusting or connecting pipe B is joined to the bowl A by means of the bolts 0 and nuts 0 thereon, the heads of said nuts being inserted through the enlarged openings b and slid into the slots or elongated openings Z), which, as before stated, have their sides beveled, so as to receive the tapered heads of the bolts. The pipe B passes through a suitable opening e in the flooring E and engages the internally-screwthreaded portion of the opening cl in the upper end of the elbow, in which position said pipe is secured by means ofalock-nut D,between which and the upper end of the elbow C may be placed packing e of any suit-able kind, but usually of fiber. The elbow C is provided in each of its sides, nearits bend, with openings f and f, to which the vent and flushing pipes may be connected in any suitable manner.

From the foregoing and by reference to the drawings it will be seen and clearly understood that when the parts are in position, as above described, the bead 7?, on the lower edge of the flange B of the pipe B, which pipe and flange are preferably made of brass, will rest on the floor E just inside of the downturned portion a of the flange a of the bowl, which flanges are bolted together, as before stated, and that the elbow C may be secured in position at the proper point on the pipe 13 and there locked by means of the locking-nut D, thus affording a connection which will be perfectly tight at its joints, so as to prevent the leakage of water or gases, and one that can be readily and economically placed in position.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination with the bowl having at its lower portion a horizontally-extending flange provided with a series of openings and at its outer edge with an annular downturned portion, of the externally-screw threaded connecting-pipe carrying on its upper end a flange t0 fit within said annular portion and to rest on the floor, said flange being provided with a series of apertures comprising an enlarged opening and a slot extending inwardly therefrom, the walls of said slot being downwardly and outwardly inclined, bolts having tapered heads located in the enlargement of the said slots and extending through the openings in the flange of the bowl, an elbowpipe having an enlarged and internallyscrewthreaded upper end to receive the screwthreaded portion of the connecting-pipe, and a lock-nut on the connecting-pipe at the upper end of the elbow-pipe, substantially as described.

2. In a pipe connection, the combination with the elbow-pipe having an enlarged and internally screw-threaded upper end, of the externally-screw -threaded connecting-pipe inserted therein, a flange on the upper end of said connecting-pipe for connection with the bowl and to rest on the floor, the said flange having a series of apertures each of which comprises an enlarged opening and a slot extending inwardly therefrom, the walls of said slots being downwardly and outwardly inclined, and a lock-nut on the connecting-pipe at the upper end of the elbow-pipe, substantially as described.
